Dell PowerConnect 55xx Systems User Guide

As shown in Table 21-1, the DHCP Snooping Binding database is updated by 

interception of DHCPACK, DHCPDECLINE and DHCPRELEASE packets, 

and is stored in non-volatile memory.
Even if a port is down, its entries are not deleted.

 

NOTE: 

Only DHCP requests on untrusted ports are maintained in the Binding 

database.

Limitations

The following limitations apply:

• Enabling DHCP snooping uses TCAM resources. 
• The switch writes changes to the binding database only when the switch 

system clock is synchronized with SNTP.

• The switch does not update the Binding database when a station moves to 

another interface.

Global Parameters

Use the 

Global Parameters

 page to:

• Enable/disable DHCP snooping globally.
• Determine whether to forward or filter DHCP packets received from 

untrusted interfaces, whose source MAC address and the DHCP client 

MAC address do not match.

• Determine whether to forward or filter DHCP packets, received from 

untrusted interfaces, with option-82 information. 

• Set Binding database update interval.
